Katana risked expulsion from the magic academy to steal an enchanted elixir per her boyfriend's wishes, but when he tells her he won't be able to visit her for a few hours, her curious nature gets the better of her and she samples the potion. Immediately overcome with lust, she cannot keep from plunging her hands between her legs and pleasuring herself! She's so engrossed in her actions that she fails to notice the entrance of the Head Mistress, who decides that if she wants to play with magic, she'll be given a crash course in exactly that! In a flash, she's magically reduced to just her underwear, however, her panties have been replaced with a medieval leather chastity belt! Worse, she's been gagged with ultra sticky magical tape, and her hands have been locked into enchanted cuffs! But none of that compares to the ultimate torment: the elixir has only grown stronger in her system, and now she cannot possibly relieve herself! She rubs and rubs at the belt, desperate to give herself some relief, but it's no use! And, to add insult to injury, the Head Mistress locks her in a magic trunk to ship her back to her parents, to see exactly why their unruly student got herself expelled!

Dahlia is home alone when she spots an intruder at her window. The masked figure disappears, and she assumes it's just a bad dream. Dahlia decides to watch TV to distract herself, but her screen glitches and turns into a spiral. The intruder sneaks up behind her and makes her watch the screen, melting her mind away before fucking her.

Villainous Katana has created a secret formula that gave her a cock that bimbofies anyone who encounters it! She lures her arch-nemesis, SuperDahlia, to bring her down once and for all. SuperDahlia is surprised by Katana's new cock, but tries not be distracted as she attacks Katana. However, Katana's cock is already taking control and Dahlia is too weak to fight!

She falls to her knees, face to face with the magical cock. She feels her brain slipping away and her body begin to change, and before she can resist, Katana shoves the cock in her mouth. Dahlia's brain is instantly sapped and she begins to suck mindlessly.

Katana cums in Dahlia's mouth, which briefly startles her out of her trance. It's too late however, and her body has already begun to change. She grows long pink nails and her hair turns blonde. She whimpers and begs to be turned back as her tits grow so big they burst through her costume! She tries to fight Katana again but is easily subdued. Katana brings her to the bedroom and easily throws her on the bed. Dahlia is dazed and bimbofied as Katana fucks her and cums in her, filling her with a potent dose of the transformative cum.

Dahlia goes completely mindless as Katana gloats. Her tits grow to an enormous size and her brain is permanently erased. She is now just a brainless bimbo pet for Katana.

On the way to visit her granny, Dahlia runs into a big bad wolf in the woods. While she talks about her encounter in the woods, she notices that her granny looks a little different. Granny's hands, ears, and eyes look bigger. Before she can resist, Dahlia gets tricked by the wolf! With Dahlia under her spell, the wolf decides that she wants to make Dahlia her personal slut. She begins her training, deepening her power as she fucks Dahlia's mind away.

Dahlia is a trick-or-treater dressed as a cow. She knocks on a door, and is told that they are out of candy but have some in the house. Dahlia enters the home, only to get tricked with a cock in her face! The cock sways back and forth as Dahlia's thoughts melt away. She starts worshipping it, which slowly turns her into a cock hungry hucow.

Katana está completamente amordazada con una mordaza de bola cubierta de cinta de microespuma. Está atada de rodillas con cinta adhesiva. Dahlia besa, lame y acaricia sensualmente la mordaza de cinta, admirando cómo resalta los labios de Katana y amortigua sus gemidos.

Katana es una reportera que ha estado investigando a la Dra. Dahlia, una doctora corrupta que ha estado realizando experimentos poco éticos en sus pacientes. Katana entra a la oficina disfrazada de paciente, pero la doctora se da cuenta y ata a Katana a la mesa de examen. Ella coloca sondas en la cabeza, las tetas y el coño de Katana que envían señales eléctricas para electrocutar el cerebro de Katana. Dahlia luego inserta un espéculo en el coño necesitado de Katana, y decide que su paciente está lista para ser convertida en un juguete para follar. A Katana le follan el resto de sus pensamientos con una máquina folladora y ahora es la rata de laboratorio perfecta de la Dra. Dahlia.

Dahlia va a ver al fabricante de marionetas Katana y le confiesa su mayor deseo: quiere ser convertida en una marioneta de madera. Katana está dispuesta, pero le advierte: si pasa por este cambio, quedará completamente indefensa, incapaz de hablar o moverse sin que tiren de sus cuerdas, y pertenecerá por completo a su dueño. Esto es exactamente lo que Dahlia desea, y firma el contrato con entusiasmo.

Katana comienza la transformación, pintando costuras de muñeca en la piel de Dahlia. La pintura empieza lentamente a hacer efecto en la mente de Dahlia, haciéndola más lenta y volviéndose rígida y ligera. Es completamente incapaz de moverse por sí misma o hablar para cuando Katana llega a pintarle la cara con rubor y lápiz labial como los de una muñeca. Katana la viste con ropa y cabello más apropiados para una marioneta, luego le ata largas cuerdas a las extremidades. ¡La marioneta está casi completa! Katana busca un dueño para la marioneta mientras lo último de su mente humana se desvanece. Katana prueba la nueva marioneta haciéndola bailar sobre sus cuerdas, demostrando que ahora es un objeto perfectamente indefenso.

Más tarde, la transformación se ha completado del todo. Katana ha encontrado un comprador para la muñeca y se despide de ella. El nuevo dueño viene y examina a la muñeca, manoseándola, metiéndole los dedos en la boca e inclinándola hacia adelante para inspeccionarla.

La Dra. Katana está trabajando en un nuevo suero de bimboficación cuando Dahlia irrumpe en su laboratorio. Katana ve esto como una oportunidad para probar su nuevo producto y le da el suero a Dahlia mediante un beso. Al principio Dahlia se resiste, pero Katana activa el suero haciendo que Dahlia tenga un orgasmo. La heroína pierde gradualmente su inteligencia y capacidad de hablar. El cabello y las uñas de Dahlia crecen más largos, su maquillaje se vuelve más atrevido y sus tetas crecen enormemente mientras su cerebro se encoge. Ahora Dahlia es la primera bimbo exitosa de la Dra. Katana. 

Katana was all set for a quiet evening snuggled in her comfy clothes and socks when her boyfriend presented his latest strange invention: a magic spray that imbued objects with the power to move all by themselves! Ignoring his warnings, Katana carelessly sprayed the potion around the room, and scoffed as nothing happened. Of course, she failed to realize that when the mist sunk to the ground and settled, it would cover her boyfriend's rope kit! Now, with the ropes alive and determined to get some exercise, Katana found herself helplessly bound and gagged! She hopped about the apartment trying to free herself, only to realize she was helpless in their tight grasp! Struggling to her phone, she managed to use her cute little nose to dial her boyfriend, but thanks to the fat gag in her mouth, he couldn't understand her! Katana was left with no alternative to fight against the ropes, but the ropes had other ideas, and cinched her into a brutal hogtie that left her barely able to twitch! Poor Katana would be stuck until her boyfriend came home, but little did she realize he had his own surprises in store for her!
